A lawsuit alleges that a 295-pound Newton police sergeant broke a man’s collarbone in an arrest after a car chase, that other officers piled on and that the man then suffered with a severe fracture for two weeks in the Sedgwick County Jail without getting medical care that he needed.

The lawsuit complaint, filed on Jan. 14 in Sedgwick County District Court, says that officers “conspired to hide evidence regarding their use of excessive force, including a video of the encounter.”

Newton City Attorney Bob Myers said Friday that it is too early in the legal process for him to comment.

The 12-page complaint also alleges that the Sedgwick County Jail has a “de facto policy of avoiding medical care” for inmates.
